CLIO B. YAW, Oi ARLINGTON, NEW JERSEY, ASSIGNOR TO REMINGTON TYPEWRITER COMPANY, OF ILION, NEW YORK, A CORPORATION OF NEW YORK.

TYPE-WRITING MACHINE.

To all, whom it may concern: Be it known that I, 01.10 B. Yaw, a citizen of the United States, and resident of Arlington, in the county of Hudsonand State of New Jersey, have invented certain new and useful Improvements in TypelVriting Machines, of which the following is a specification.

My invention relates to typewriting machines and t0 tabulati'ng mechanism.

One object of my invention is to provide means whereby the tabulator may be embodied within the body of the, machine and does not project beyond the outline of the frame of the machine, and to provide means whereby access may be readily had to certain of the tabulator stops by swinging back the platen.

A further object of my invention is to provide means for automatically locking certain of the tabulator stops against displacement when the platen is moved down to 0perative position.

To the above and other ends which will hereinafter appear, my invention consists in the features of construction, arrangements of parts and combinations of devices to be hereinafter described and particularly pointed out in the appended claims.

In the accompanying drawings wherein like reference characters indicate correspomling parts in the various views, Figure 1 is an enlarged detail fragmentary vertical fore and aft sectional view taken on the line 0-4: of Fig. 2 and looking in the direction of the arrow at said line, the view showing a sutlicient number of parts of one form ol typewriting machine to illustrate my invention in its embodiment therein. Fig. 2 is a fragmentary vertical transverse sectional View of some of the parts shown in Fig. l, the section being taken on the line g g of Fig. 1 and looking in the direction of the arrow at said line. Fig. 3 is an enlarged detail plan view showing the column stop bar and the means .lor mounting the same, some of the parts being shown in section.

I have shown my invention embodied in the present instance in a trout-strike machine wherein the type ba rs u strike against.

the front face of the platen, though it should be understood that from certain aspects of Specification of Letters Patent.

Application filed July 30, 1909.

Patented Nov. 8, 1910. Serial No. 510,405.

my invention it may be embodied in other styles of typewriting machines.

The f ame of the machine comprises side orend plates 1 united by av front cross plate (not shown) and a rear cross plate 2. Fixed guide rails 3 are supported on the side plates and are grooved on opposite sides for co operation with anti-friction balls or rollers 4t which are likewise received in oppositely grooved rails 5 of a carriage truck (3. The carriage truck is thus'supported for movement from side to side of the machine. The carriage truck is provided with end bars 7 having angular recesses 8 formed therein (see Fig. 3) for the reception of a column stop bar 9 squared at its ends for the reception in the squared openings 8 in the ends of the truck. The upper face of this bar is provided with indices 10 corresponding to the carriage scale. Tapped openings 11 extend through the end bars 7 of the truck and receive headless screws 12 with reduced unthreaded ends 13 which are'received in I From an inspection of Fig. 3 it will be observed that the ends of the column stop bar terminate short of the bottom walls of the opening 8 so thatv the screws 12 provide means for effecting a longitudinal adjustment of the column stop bar by turning one screw out and the other in and the bar is held by said screws against longitudinal movement on the truck when the desired adjustment has been attained. The column stop bar is prevelited from a rotative movement by the squared ends thereof being seated in the squared openings 8 in the truck. The column stop bar may be readily detached from the truck by withdrawing both of the screws 12 from the openings in which they are seated in the column stop bar.

The ba t) is toothed as indicated at 14 on opposite sides thereof to provide iuterdei'ital spares between the teeth for the reception of bifurcated colunurstops 15, the depending arms 16 of which extend below the column stop bar and are cooperative with a. suitable tabulating stop or stops which in the pres ent instance are illustrated as a series of tlemnuinational stops 17 actuated by any suitable n mus, and each adapted to receive an upward movement into the path of the depending arms of the column stops.

he character of the tabulating means which .1 oo-act with the column stops 15 is immaterial forythe purpose of the present lnventicnf Theends of the truck are formed with upwardly extending lugs or projections 18 apertured to receive the ends of a shaft 19 which-turn freely in the bearing openings pl'aten-frame'and shaft 19 are fixed to turn in said lugs. A platen frame 20 has apertured portions 21 which surround and are fixed to the shaft 19 by pins 21 so that the together. The platen frame is likewise provided with hearing openings to receive a laten shaft 23 of a cylindrical platen 24. spending feet 25 on the platen frame are adapted to rest upon the forward rail 5 of thecarriage truer when the platen frame is in the normal position assho'wn in full lines in Fig. 1. A sleeve or hollow rock shaft 22 is adapted to turn freely on 'the "shaft 19, and is provided with a finger piece or arm '26 fixed to the left-hand end of the hollow shaft and adapted to rotate it on the" roundsthe hollow shaft 22 about midway in its length and has its ends united by ashaft19. A split sleeve 27 (see Fig. 1) surwiheaded screw 28. An arm 29 extends fol wardly from the split sleeve 27-and is aper- 30,

f bar. 31 cooperate withhangers 32 formed in Fig. 2. The endportions of this locking .with sleeves 33 which surround and areloose upon the hollow shaft 22 so as to render 1 =-t-hem' independently movable.

Screws 3 1 loosely connect the hangers 32 with the bar a 31. The hangers 32 are adapted to receive 1 ."the ends of a shaft 35 which supports paper feed rollers 36. A leaf spring 37 is secured byiscrews 38 to the platen frame and bears at-its free end against a projection 39 on the arm or finger piece 26. The pressure of the A spring is exerted to turn th'eQfingerpiece 26 v 1n, the direction of the-arrow b in Fig. 1,

. thus exerting a pressure which turns the ;.50', Y movement of-the bar-31 and the latter-presshollow shaft 22 so .as to effect an upward ing against the hangers 32 'm'aintains the feed rollers in contact with the platen or the paper thereon. When thefinger piece 26 is moved forwardly, in the; opposite direction from that indicated by the arrow 11 in Fi 1,

the bar 31 will be moved downwardly, t us lreleasing the pressure on the hangers of the" paper feed rollers and allowing the feed rollers to be cast off, I I I From an inspection of Figs. land 2 itwill be seen that the column stop bar 9' issituated beneath the platenframe and below the laten and that the so-called locking bar 31 is normally maintained above the series of column stops 1,) and prevents thecolumn stops from being moved upwardly far enough to disengage them from the column 1 line position shown in Fig. 1 the column stops are uncovered, giving ready access to the column stops, to enable them tobe ad j usted, from'th'e front of the machine to different positions along the column, stop bar;

Moreover, the act of swingingthe' platen back to the dotted line position carries the locking bar 31 ,to a position where it is no longer in'coiiperative relation with the column stops to maintain them locked on the column stop bar, so that they may at this time be readily removed and adjusted along the bar. When the platen is again swung down to the full line position in Fig. 1, the bar 31 is moved to the locking position, thus automatically lockin the column stops against detachment from the column 'stop bar29. In order to limit the swinging movement of the platen frame I have rovided stop pins 40 on the platen frame w ich cooperate with upwardly extending stops 41 formedon the bearing lugs 18 of the truck.

It will be seen that the tabulator of my invention iswhat' may be termed a built in ta'bulator being contained wholly within the body of themachine and doesjnot project beyond the outline of the frame as in most of the tabulators heretofore devised.

While I have shown and described, the locking bar 31 as part of the paper feed mechanism and whereby spring'pressure is applied to the paper feed rollers and whereshould be understood that the locking bar may be carried by the'platen frame in any suitable manner and that its sole function .may be to lock the column-stops in place when the laten'is in the operative posltion,

so far as t e broaderaspects of myinvintion are concerned.

The paper feeding mechanism herein shown and described is claimed as such me.
